Well, this move does not work so it was better to leave it as a ko threat. White's only chance left is to do massive damage to Black's territory on the bottom--by living there or by killing the bottom-left corner. Therefore, White should aim at the cut at "a." I did not read here, but perhaps White can start with some move in the marked area:

Game line is different now.

I guess something like that could happen, with :w50: connecting and maybe some other :w48:

I am trusting that this should be sente since now I can cut his group in half.

This game's exciting! ... and to think opex was almost ready to throw in the towel at one point. Never give up, never surrender! :D

There is a problem for Black here. Black intends to cut White if White tenukis. However, cutting takes away liberties from his own group on the right, potentially leading to a huge ko fight:

If Black responds to this move, then White lived in sente, letting him come back to defend his group on the left. In other words, this would mean that White tenukied and got away with it, absent consequence. If Black does not respond to :w4:, on the other hand, White will begin the ko:

I don't think Black can fight this ko. Therefore, this option is no good for Black, either ... and that's assuming White has to play :w4: and can't tenuki again at that point.

In any case, Black suddenly seems to be in great deal of trouble. The blunder on move 145 may well come to cost Black the game.
Edit:
White might consider to play the following move, which completely cuts Black group off while defending the cutting point at "a":

I was looking at this too, but with :w1: one space to the left. White would still have miai to connect after blocking below A if black tries to wedge in, either capturing black's wedging stone or the other stone in a very short ladder. On reflection, though, that doesn't work after black extends to your :w1:. With this, though, things get complicated after black tries to cut the keima. Lots of ko threats for the left, and black doesn't have time to both eliminate the ko and the cut/connection by white.

Looking back, I think black should just have connected at 133 and then fought it out on the left without having to worry about his main group. I've copied that position below.

125 as well (marked) did not really pressure any of white's groups and allowed white the marked move to eliminate his group worries and allow a more severe attack, though I think black was still ahead. If anything, I'd be tempted to have played it a line deeper, to make it easier to live underneath if it is cut off.

Now that I look at the position, perhaps White should not allow Black to play :b1:, so maybe White should play there himself:

Alternatively, White may consider to deny Black an eye on top, via the following move:
